电网智能模糊控制器的干扰源分析及屏蔽

Design of EMC on Controller of temperature and humidity in HV switchgear

电网智能模糊控制器由于应用于高电压及复杂电磁环境场合,必须准确分析电磁干扰源并设计屏蔽干扰的措施,才能保证设备的安全运行。本文首先讨论了外部骚扰源的产生原因,着重介绍防静电放电(ESD)干扰措施,防辐射电磁场干扰措施,抗衰减振荡波干扰措施,抗浪涌(冲击)干扰措施,抗快速瞬变脉冲群干扰措施。并提供了在实验结果的基础上改进的方法。其次讨论了内部骚扰源抗干扰设计时着重考虑的问题,对软件抗干扰的设计做了简要说明。

The controller of temperature and humidity for HV switchgear, because of applying in high electric voltage and the complicated electromagnetism situation, must be resolved the electromagnetism and permit the problem then can guarantee the equipments safe circulating, this paper discusses the exterior interference of creation reason, emphasize to introduce the anti-static measure, the anti-radiation measure, the anti- osciUatory waves measure, the anti- surge measure, the anti- Electrical Fast transient/burst measure, Provide also the method of the improvement based on the experimental result, Secondly discussed the inner anti- interference design, made a brief account of the software anti- interference.
